Grundfos SQFlex Solar Water Pumps
The SQFlex solar water pump incorporates built-in protection features to guard the pump. The built-in protection features help the water pump to protect against overheating and overloading and prevents the pump from running dry. There is an automatic restart system in the solar water pump to start the pump. The built-in protection feature monitors the voltage and load conditions of the solar water pump. The SQFlex water pump is equipped with helical rotor pump. The bearing system is made of carbon or ceramic to provide reliability. The pump casing is made of stainless steel to provide long service life.
The SQFlex solar water pump utilizes a single motor with segmented stator to pump water efficiently. The micro frequency converter of this pump system transmits power to the motor. This pump incorporates a Maximum Power Point Tracking system for system efficiency. With the two-way communication process that takes place between the pump and interface box, additional wires are eliminated. This solar water pump from Pacific Energy Company can work at any voltage between 90V and 240V AC or 30V and 300V DC.
